PhishBlock is a Chrome web browser extension. It helps to block phishing through email:
- checks the sender's email address and compares it to all the links in the email to see if they come from the same place (domain checking)
- adds a red box around any suspicious link data and around attachments
- adds a reminder to check the sender's email and any attachments (make sure they are expected)
- removes all links from the email (We should't be clicking on links in email! It's best to go to the bank's website and get the message or other information there, for example.)
Currently the extension only works with Gmail.
